Summary: minor, tweak SXE_CHECK_LINKER_FLAGS

Keywords: bldchn

Just to be symmetric provide a 4 argument version for macro
SXE_CHECK_LINKER_FLAGS, where the 4th argument is a list of additional
flags to pass to the linker, in analogy to the 4-arg version of
SXE_CHECK_COMPILER_FLAGS.

* m4/sxe-linker.m4: provide 4 argument SXE_CHECK_LINKER_FLAGS for
  analogy reasons
